In the past life, Xu Donghai sold his boat and left home, causing his wife to plunge into the sea and die, and his twin daughters refusing to acknowledge him. Reborn back to the day of selling the boat in 1994, he jumped off the boat back to shore in public, swearing never to fail his wife and daughters again. The ancestral bronze medallion turned into the tidal treasure map, helping him dig out full baskets of seafood on the empty beach, find hidden fish schools in the dead trench, shock the whole village with rare seafood, and lead the villagers to get rich. However, making money is easy, winning back hearts is hard. Facing his wife who guards against him and daughters who refuse to call him dad, can Xu Donghai use promise-keeping returns time and again to piece the broken family back together completely?
